Coupling with renewable energy sources, the proton-exchange membrane electrolyzer cell (PEMEC) is a promising alternative for sustainable energy storages. As a key component, the membrane electrode assembly (MEA) plays an important role in the PEMEC performance and efficiency. Many materials cannot be utilized as the liquid/gas diffusion layer (LGDL) of MEAs at the anode side of PEMECs due to the high anodic potential and oxidative. A high entropy alloy (HEA) – Al0.3FeCoCrNi has received considerable attentions as a highly-promising material due to its high corrosion resistance in harsh environment. In addition, Al0.3FeCoCrNi provides high thermal/electrical conductivities and excellent mechanical properties. In the present research, an innovative design of a transparent test device is developed for Al0.3FeCoCrNi. The high-speed and micro-scaled visualization system, electrochemical impedance spectroscopy, x-ray diffraction, and scanning electron microscope will be applied for in-situ and ex-situ characterizations. The HEA corrosion properties and associated parameters will also be discussed.
